For those having this problem, especially if they have SATA drives, it would probably be worth a shot to try the deadline scheduler instead of cfq.
(...)

Code:

elevator=deadline

For me this has started a nightmare. Once I rebooted the system almost stopped on the tiniest bit of disk activity. While starting openOffice Calc I had to wait 16 (sixteen!) seconds until a page in firefox started scrolling when I used the mouse wheel.

It is really frustrating that this problem seems to be so differently and widespread, that it's seemingly impossible to get a grip on (or even an idea about) what the problem actually *is*. _________________systemd - The biggest fallacies

So far so good for me! Kernel 2.6.30 was a huge improvement over 2.6.2[0-9] and 2.6.31 seem to ba as stable and fast.

I think this solve the issue in my case, 64bit Linux is now exploiting the whole potential of my computer!

EDIT: Ignore my comment, skip this kernel, it suck, I am reverting to 2.6.30 right now.

what happened? elaborate please.

Simple, the mouse freeze once again and the system become unresponsive when I emerge something, even the sound lagg, It was almost perfect with my old 2.6.30-rc5 kernel.

i follow this thread since some time...
and it is hard for me to confirm anything from what U said.
of course it has some troubles, but i cannot say it depends on amd64 arch...

@Belliash:
Mouse freeze seem to be the common denominator of this problem, if you don't experience them, then you don't have the problem. Firefox is slow under Linux and even more in 64bit Linux (no asm optimisation). But that not related to this problem.

I am back to 2.6.30-vanilla-rc5, until now, it is the best kernel I have tried (I tried 2.6.30-r* too). I think I am going to stay with this one for a long period of time. I upgraded it to GCC 4.4 and disabled kernel hacking, it work even better.
